Product Name: Tin Oxide
Product Description: Tin(IV) oxide appears as a white to slightly gray powder, with a density of 6.95 g/cm³, a melting point of 1127°C, and sublimation at 1800°C - 1900°C. It is soluble in H2SO4 and hot concentrated HCL, slightly soluble in NaOH or KOH solutions, and insoluble in water, alcohol, ammonia water, and cold acids. When fused with hot concentrated NaOH (KOH), it forms sodium stannate, and it does not react with nitric acid.

Application: | Manufacturing of tin salts: Different combinations with chromates, lime, vanadium, chlorine, etc., in pigments yield various colors such as pink, beige, yellow, and purple-gold. These are used as coloring agents for ceramics and enamel, glass polishing agents, in the production of opaque glass and opal glass, as mordants and weighting agents for textiles, analytical reagents, polishing agents for steel and marble, catalysts for organic synthesis, and in the production of enamel and electromagnetic materials. | |||||
